Gas prices slip under $4 as Iran deal reshapes oil outlook

Gas prices in the U.S. have fallen to a national average of $3.99 per gallon, dipping below $4 for the first time since mid-April, as oil markets react to news of a potential U.S.–Iran framework to reopen the Strait of Hormuz. Brent crude dropped sharply, signaling relief ahead, but analysts caution that pump prices may not fall immediately and real relief could take months as reopening efforts proceed and oil flows normalize.
